Autologous HSCT for Relapsing-Remitting Multiple Sclerosis
Three examples of different myeloablative BEAM/ATG (carmustine (BCNU), etoposide (ETP), cytosine arabinoside (Ara-C), melphalan/anti-thymocyte globulin) conditioning regimens for relapsing-remitting multiple sclerosis.

Refer to details in each hematopoietic stem cell transplantation publication, as these are 3 examples and not all the variations in BEAM/ATG and G-CSF dosing strategies.

(A) BEAM/ATG over 7 days
(B) BEAM/ATG over 6 days
(C) less intense mini-BEAM

ATGAM = anti thymocyte gamma globulin (equine origin)
rATG = rabbit origin anti-thymocyte globulin
G-CSF = granulocyte colony stimulating factor
HSC = hematopoietic stem cell.
Common non-myeloablative regimens for RRMS

A - cyclophosphamide/antithymocyte globulin
B - cyclophosphamide/rituximab (verbal communication Dr. Federenko, Moscow, Russia)
C - split dose cyclophosphamide/ rituximab

G-CSF = granulocyte colony-stimulating factor,
HSC = hematopoietic stem cell,
rATG = rabbit anti-thymocyte globulin.

Uppsala (Uppsala, Sweden) and the other from Northwestern University (Chicago, US).
Both studies demonstrated dramatic improvements in neurologic disability of a magnitude that had never previously been reported in clinical trials with DMTs.

Since then several studies of HSCT performed predominately or solely for RRMS have been published with similar results (Table 41.1).

To better understand the profound effect of HSCT for MS, the data were collected before some of the highly active DMTs were licensed, and being a real world setting, a percentage of patients could have been off treatment for variable periods of time.

In comparison, after HSCT for RRMS, NEDA is roughly 70-90% at 2 years and 68-80% at 5 years

NEDA, while a useful clinical endpoint, does not capture improvement in neurologic disability that is most often measured
